3 Claims.

This invention relates to a carrier and protector for bricks, both for the purpose of putting the bricks in packages of convenient size and weight for handling, storing, or shipping, and also for the purpose of protecting them from chipping and abrasion.

Carriers and protectors of this general character are already known and used in the brick trade, but have various disadvantages, the principal 1 one being that a holder made'for a certain size of brick cannot be employed for bricks of any other size, and consequently the brick manufacturer or brick dealer who is packing bricks in such holders is obliged to keep a stock of several sizes of holder to conform to the various sizes of brick in which he deals. Also, such holders at present known are of unnecessarily bulky material and are subject to partial crushing of the holder in shipping and handling with consequent reduction of its thickness. This is particularly disadvantageous in shipping carload lots by rail, or in long-distance truck shipments since it gives the result that a load which is tight at the beginning of the journey may have several inches playafter a few hours of travel, with resultant shifting of the bricks upon one another.

My invention therefore aims to eliminate the two difficulties mentioned as well as others, all of which will become more apparent as the specification proceeds.

I so construct my holder that it can be supplied to the users in packages of flat blanks, which blanks can be set up at the brick plant by unskilled labor without needing any additional materials whatever either in the way of rivets, staples, paste, or otherwise; and the sameblank may be so set up into a holder of any of a plurality of desired dimensions within a range sufficient to cover a variety of brick sizes. Thus the user has only one holder sizeto keep in stock and no other supplies whatever are needed.

Building bricks are sufficiently standardized so that normally a single blank arranged to be folded into only two different sizes is adequate to take care of the usual line of single and double building bricks, as will appear from the detailed description below. In the case of fire brick and other specialized products, where the variation of dimensions is different in range and character from building bricks, the principles of my invention are still applicable, although the blanks which form the holders may not be of the same basic sizes as are supplied to the building brick trade.

Although I show and describe the preferred form of holder as made from a blank having only a double variation in size, it will be understood that this showing is not limiting, but merely one which is convenient for use with building bricks. Any number of variations of size may be provided 5 for in a single blank.

A further advantage of my invention is that by reason of a suitable arrangement of parts which are to interfit or to be juxtaposed when the blank is set up, I am able to use thinner and 10 stiffer material than has hitherto been considered satisfactory where a tray or carrier function as well as a shielding effect has been needed.

To the accomplishment of the foregoing and related ends, the invention, then, comprises the 15 features hereinafter fully described, and particularly pointed out in the claims, the following description and the annexed drawings setting forth in detail certain illustrative embodiments of the invention, these being indicative however of but 20 a few of the various ways in which the principle of the invention may be employed.

In the accompanying drawings which illustrate a preferred embodiment of my invention, and modifications,

Fig. 1 shows the preferred blank;

Fig. 2 is a perspective of the complete holder set up from the blank of Fig. 1 for one size of brick;

Fig. 3 is a perspective showing one end only 30 of the holder set up from the blank of Fig. 1 for another size of brick;

Fig. 4 is a perspective showing one end only of a modified holder set up for its greatest length;

Fig. 5 is a perspective illustrating a portion of 35 a pile of holders, set up as in Fig. 2, filled and stacked; and

Fig. 6 is a view similar to Fig. 5, but with the holder set up as in Fig. 3;

Fig. 7 illustrates a modified blank;

Fig. 8 illustrates the blank of Fig. 7 set up for its greatest length;

Fig. 9 illustrates another modified blank; and

Fig. 10 illustrates the blank of Fig. 9 set up for 45 its shortest length.

The blank consists of a single piece of suitable material, preferably not corrugated, such as folding box board or any of a variety of materials which are cited in more detail hereafter. In Figs. 50 1, '7 and 9, all of which illustrate blanks ready for folding, the broken lines indicate creases on which bends may be made, and the solid lines indicate cuts entirely through the material..- All creases and cuts are designated by reference numerals. 55

and F. There are also three small areas G, H

and J, whereof G may be used as a part either of A or D, H may be used either as a part of D or as a flap, and J may be used either as a part of B or a part of The periphery of the blank comprises edges H to IE inclusive, and hooked tongues 3| and 32.. Slits I7 and 8 extend from the periphery inward a sufficient distance to separate areas C--E and areas DG-FJ.

Only one end is shown as variable, since sufficient size range for standard singleand double building brick can be so attained. There are consequently two sets of fold lines, 3-4 and -|-8, at the right end of the blank, corresponding respectively to 2 and 6 at the left end, and the right end has two slots, 22 and 23, either of which i may receive the hooked tongue 32. r

The assembly of the shield ortray setting up the blank is apparent by comparison of Figs. 1, 2 and 3. To make a shield of the full length possible the back B andends C and ,D are turned up along the respective bend lines I, 2 and 4 into vertical positions, the area G becomes part of the bottom A, and the area H becomes part of the end D.- The laps E and F are brought outside their respective ends C and D and the tongues 3| and 32 are hooked into their respective slots 2| and 22, allas will be seen in Fig.2.

To set up the shield in its longer form, the end D is folded along the line 3, so that the area G alsobecomes a part of the end. The area I-I functions only as a flap, bending down along the crease line 5 into the dotted line position H of Fig. 3, giving additional protection to the topof the end brick, as shown in Fig. 5, and the tongue 32 is fastened into the slot 23.

In making the shield the height of the back B and end C is preferably left slightly greater than the height of the bricklto be'placed therein, with the result that a narrow strip 50 alongthe edge l4, that is, along the top of the back B, and a similar narrow strip 5| along the edge |2 be-' comes folded over when the successive loaded carriersare piled. Folding creases are not formed in the blank for these narrow strips, since these strips 50 and 5|, somewhat exaggerated in Fig. 5,.neednot be of regular formation. a

As shown in Figs. 5 and 6, when -the loaded shield orholders arestacked, every brick has all surfaces protected by its own or another shield except those surfaces which abut other bricks within the same holder. Protection on these interior surfaces may be provided by pads such as 52, Fig. 5, between'the bricks within the shield. Pads are especially desirable whereornamentab face bricks are packed because the pads protect the edges of the wall-faces from chipping or -other injury; These pads are simply fiat pieces,

usually of some sort of paper material, for example,the same material as the shield. Although pads are favored in the industry, they may be dispensed with when using my improved shield, because only a. few bricks are in each shield,.and because the bricks fit snugly in the shield and are incapable of movement against one another; also, usually the ornamental wall-face, which is exposed in the holder-for inspection, is protected by the bottom of thenextuppershieldl in the pile; In detail, one of the narrow faces andv one end of each brick areprotected 'by the areas A folding along the line |25.

and B of the shieldin which the brick is carried, while the wall-face is protected by the bottom of the next shield superposed in the pile, and the exposed end is protected by the back of the shield next in front.' 1

In the form illustrated in Figs. 1, 2 and 3, only. I two different set-up sizes of the shield (or holder) are provided for although it is apparent that provision might be made for more sizes by increasing the number'of bending creases and the number of fastening slots at one end or at both ends.

Fig. 4 illustrates such a modification, showing "the left end only. The right end may or may not bea duplication of the left. Three size possibilities are present in Fig. 4. The bottom, A, has two additional areas, A and A and the back, B, has corresponding additional areas, B and B which'may be included or not in the extension of the shield when set up. Appropriate bending creases |2|, |22, I23 are formed in the 20 bottom, and GI, 62, .63 in the back; besidesslots 2| 2|2, 2|3, to take a hooked tongue 3 on the end of the lap E. In Fig. 4, the shield is'set up for the greatest longitudinal extension. For the next shorter length,- the bends would be along the creases I22 and 62,- with the tongue 3 in the slot 2|2, while for the shortest the bends would be at |2| and 6|, with the tongue in 2| In order to dispose of excess height of theend C when the shield of Fig. 4 is made up in one of its shorter lengths, creases |and J26 are formed parallel to the upper edge of the end C. Thus, if the shield of Fig. 4 is folded along the lines 62-- |22, the upper part of the edge C will be folded down along the line |26, ina manner similar-to that shown at H in Fig. 3. Corre spondingly if the end C isv defined by folding on the lines 62|2|, it will stand up corresponding ly higher, and its upper portion be disposed by ,Fig. 5, besides demonstrating the general arrangement'of a pile of bricks, shows four double I sized building bricks in each shield, the shields being set up full length asin Fig. 2. Pads 52 are shown in' Fig. 5. Fig. 6 shows in like manner. the shields set up short as in Fig. 3, each loaded with eight single building bricks, and stacked. Pads are omitted from this figure.

For additional edge protection, such as given by'the strips and 5|, the blank may be cut 5. a

with an additional flap such as the area K01 Fig. 7 or L of Fig. 9. The area K is a continuation of the back area Band separated from that area by a crease |4|. In order to permit this area orflap K to accommodate itself to the length 55 variations, the crease l of Fig. l is continued across K asindicated in Fig. 'lbythe reference character 1|. With the foregoing exceptions Flg.- '7 is identical with-Fig. 1, although it may be otherwise modified to include additional length 00. I

adjustments in accordance with the arrangement of Fig. 4. In like manner Fig. 9 illustrates amodlfication 'i in which the additional flapformed by the area a L is included as an extension to the bottom A, 68 from which it is divided by-a crease The crease 350i Fig. 1 is continued across L and is indicated in Figs. 9 and 10 by the reference char-. acter 3|0, forming an end tab M. The tab Mot, Figs. Qand 10 is not in the way when the .tray is 70 set up for short length, and is needed when set upat full length. I I 1 These flaps K and L may also both be applied to the same blank. Whether'used together or singly, their disposition is as indicated in Figs. 8 7s and 10 respectively. That is, the flap K can either be laid back or forward. When laid back it protects the exposed upper edges of the bricks in the next carrier to the rear in the stack, and when folded forward it protects the rear upper edges of its own bricks. Likewise the flap L may be turned either up, horizontally-or down, according to where protection is most desired.

Other modes of applyingtheprinoiples of the to said bottom and two end laps connected to said back, longitudinal and transverse crease lines on said blank dividing the blank into said sections, said laps being adapted each partially to overlie its adjacent side in the set-up shield, means on said laps cooperable selectively with means in said sides to interengage to set up the shield, said transverse crease lines being in parallel plurality across at least one end of the blank, aligned across an adjacent lap and side, and said selectively cooperable means including elements in spaced relationship equal to -the longitudinal spacing between the crease lines of the parallel plurality.

2. A blank for forming a brick shield, said blank comprising a bottom, a back, sides, and

side fastening laps, a longitudinal fold line separating said bottom and said back, a transverse fold line separating said bottom from one of said sides and said back from one of said laps, a full cut separating each of said sides from its adjacent lap, a fastening hook on each of said end laps, and slits on said sides for engagement by said hooks, atleast one of said sides and side laps being further divided by other transverse fold lines, said further transverse fold lines being parallel and usable selectively to constitute hinge 5 connections between said bottom-and-side and said back-and-lap respectively; certain of said side slits being parallel andstaggered and spaced apart a distance equal to the distance between said transverse fold lines, the ultimate upper termini of said slits being stepped a distance equal to the spacing between said transverse fold lines. 3.
